Hi,

I have two webapps installed on different servers; both access the same table, which has an id of type increment:

Code:
<id
    name="idAgenda"
    column="ID_AGENDA"
    type="java.lang.Long"
    length="22">
<generator class="increment">
</generator>
</id>


This is my hibernate configuration in Spring:

Code:
<property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.jdbc.batch_size">100</prop>
        </props>
        </property>



And this is the Manager bean configuration:
Code:
<bean id="agendaManager" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
    <property name="transactionManager">
      <ref local="transactionManager"/>
    </property>
    <property name="target">
      <ref local="agendaManagerTarget"/>
    </property>
    <property name="transactionAttributes">
      <props>
        <prop key="save*">PROPAGATION_REQUIRED</prop>
        <prop key="remove*">PROPAGATION_REQUIRED</prop>
        <prop key="*">PROPAGATION_REQUIRED</prop>
      </props>
    </property>
  </bean>


Sometimes it happens that when one of th applications inserts a new record into the table, the next time the other application tries to insert, this exception occurs:
Code:

Is there something I have to configure so that both applications can insert new rows without interfering each other?

Thanx!

Nacho
